Jeffrey A. Law <law at redhat dot com> changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |law at redhat dot com --- Comment #5 from Jeffrey A. Law <law at redhat dot com> --- I wonder why forwprop doesn't simplify bb6 by pushing the RHS of the assignment to _40 into the use of _40 in the conditional. I'd guess the fortran front-end's boolean types are goofy and that's getting in the way of forwprop doing its job. It may be impeding other bits as well.
